Description

Najdluzszy czas trwania patentu do 18 czerwca 1940.W wypadku, opisanym pod A w paten¬ cie Nr 2273, dotyczacym izolowania sulfo¬ kwasów naftowych z kwasu odpadkowego, odpadki kwasowe zobojetnia sie weglanem wapniowym lub wapnem gaszonem w odpo- wiedniem stezeniu.Przy tej reakcji czesci asfaltowe, beda¬ ce pierwotnie w roztworze koloidalnym kwasnym, zostaja wytracone w postaci mie¬ szaniny siarczanu wapniowego i asfaltu.Mieszanina ta tworzy gesta mase pla¬ styczna w wyzszej temperaturze (ponad 50° C), a twardai krucha w zwyklej tempe¬ raturze i przedstawia, jako taka, znakomity materjal, zastepujacy naturalny asfalt.Zawarty w tej mieszaninie bitumen moze byc przez wyciaganie odpowiedniemi roz¬ puszczalnikami, jak benzyna, benzolem, chloroformem, dwusiarczkiem wegla i t. d. wydzielony w stanie czystym ii uzyty do fa¬ brykacji laków, masy izolacyjnej i t. p. ma- terjalów. PLThe longest duration of the patent is June 18, 1940. In the case described under A in Patent No. 2273, relating to the isolation of petroleum sulfa acids from spent acid, the acid waste is neutralized with calcium carbonate or slaked lime at the appropriate concentration. the asphalt parts, originally in an acidic colloidal solution, are precipitated as a mixture of calcium sulphate and asphalt. This mixture forms a dense plastic mass at higher temperatures (over 50 ° C) and a hard and brittle mass at ordinary temperatures. and presents, as such, an excellent material to replace natural asphalt. The bitumen contained in this mixture can be extracted with suitable solvents, such as gasoline, benzene, chloroform, carbon disulphide, and so isolated pure and used for the production of lacquers, insulating mass and other materials.

1. Zastrzezenie patentowe. Sposób oddzielania zawartych w kwasie odpadkowym po rafinacji olejów mineral¬ nych, rozpuszczalnych w wodzie, sulfokwa¬ sów naftowych od zwiazków asfaltowych, wedlug patentu Nr 2273, znamienny tern,ze cdpadki) kwasowe rozpuszcza sie w wo- sulfokwasów przez odparowanie lub tez na dzie i z tak otrzymanego roztworu wytraca drodze podwójnej wymiany zamienia na weglanem wapniowym lub wapnem gaszo- inna sól np. sodowa, amonowa i t. p. nem zwiazki asfaltowe, a z otrzymanego wodnego roztworu wydziela sól wapniowa Józef Gruszkiewicz. « Druk L. Boguslawskiego, Warszawa PL1. Patent claim. The method of separating the water-soluble mineral oils from the asphalt compounds contained in the waste acid after the refining of mineral oils from asphalt compounds, according to the patent No. 2273, characterized by the fact that acid accidents are dissolved in the sulfo acids by evaporation or also on a daily basis. He dissolves the solution thus obtained by means of double exchange, converts it to calcium carbonate or lime and converts it to another salt, eg sodium, ammonium and other asphalt compounds, and Józef Gruszkiewicz releases the calcium salt from the obtained aqueous solution. «Print by L.
